You're scared that you'll be scared, but then you realise you're scared of being scared, so then you're scared
and then you're
even more scared, because you just realised you're scared of being scared and that makes you
even more scared which makes you so scared that you're very very scared which completely scares you and you're so scared of being scared that you can't help being scared, but you're scared that you are scared... That's phobophobia for you :/
